Features

Command to run

cargo run --release -- <start_options>
  • start_options:
    • from-latest fetches the final block height from the RPC and starts indexing from that block
    • from-interruption <N?> is used to retrieve the last_processed_block_height from the database. This value is used as the starting point for processing blocks. If a specific value <N?> is provided, it will be used as the fallback option. If <N?> is not provided or if the database does not have a record (for example, in the case of a fresh start with an empty storage), the fallback option will be from-latest.
    • from-block <N> starts indexing from the block height <N>
